YARN-TREATING MECHANISM.

Application filed March 11, 1915.

To aU whom @'25 may concer/n Be it known that I, IVILLIAM J. GOING, a citizen of the United States, residing at Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Yarn- Treating Mechanism, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to apparatus for treating yarn, and particularly for washing, scouring` and dyeing it.

It has for its object to overcome some of the diliiculties which have arisen in connection with such machines heretofore known to me.

In general, such machines are in the form of rectangular vats containing the various solutions; and several of them are generally used in series, connected together to run from a single source of power, since several solutions are used in treating the yarn to cleanse it, or for dyeing. Usually the yarn is carried through the solution by a pair of aprons running over rolls or sprockets and permitting access of the fluid; the pressure between the two aprons as they run around the sprockets being relied upon to squeeze out the solution from the yarn, so that it is repeatedly squeezed and filled and thus thoroughly cleansed or thoroughly dyed. For obvious reasons it is impracticable to insure the passing opposite one another of the bars of which the aprons are composed as they progress around the sprockets and often the yarn treated in this way is not uniformly cleansed or dyed. It is also common in such machines to provide squeezing rolls at the end of the machine, or at the end of each one of the series of machines, which are kept together under heavy pressure, so that the yarn will have as much as possible of the liquid squeezed from it. These are usually covered with rubber and when they deteriorate or wear out must be removed Specification of Letters Patent.

from the machine and sent to experts for recovering. In such machines, also, the yarn is carried through by the aprons without other agitation, and the washing or impregnation with the dyeing solution thus effected is not as thorough as it should he.

These defects of machines as commonly constructed are overcome in my improved apparatus. Herein the aprons consist of sprocket chains running through the tank in several stages, carrying rigid metal bars, which are rubber covered by preference, and run on sprockets; one set of sprockets for each of the aprons is driven, so that the aprons travel at the same speed throughout; the gearing is carried on frames pivoted at one end, and I provide means for scillating the other end of the frames, so that the aprons carrying the varn are alternately raised and lowered through the liquid. This movement is counterbalanccd to save power. A portion of one apron is arranged horizontally, or approximately so, so as to provide a moving feeding table for the work, located at the entrance of the machine. I also provide a new construction of roller which will be more specifically pointed out hereinafter, and which may be repaired without taking the roll from the machine. In addition, I arrange stopping devices for the prevention of accident in such a way that the acts which are liable to cause accident themselves serve to stop the machine immediately.

The accompanying drawings show an embodiment of my invention.

In them,-I `igure l is a front elevation of a machine of the character described; Fig. 2 is a vertical section through the machine shown in Fig. l; Fig. 3 is a plan of the sprocket mechanism with some parts shown in section; Fig. 4 is a rear elevation of the machine; Fig. 5 is a detail of the apron; Fig. 6 is a perspective, broken away, of the squeezing rolls; Fig. T is a perspective detail of the improved covering for the rolls; Fig. 8 is an enlarged detail of the transfer mechanism from one of the machines to the neXt in the series; Fig. 9 is an enlarged detail in perspective of the releasing device for the stopping and starting lever; and Fig. l0 is a detail of part of an apron and roll.

I have applied reference letters with various exponents, each letter referring to special parts of the machine, as will be obvious from the description.

Referring to Figs. l to i, A is the 'trame of the machine, the various shapes of portions of which will be best understood from the drawings, and which may be varied indefinitely in shape according to the detail of the remainder of the apparatus. B is an electric motor driving the apparatus through a gear B1. A second gear B2 is mounted on a countershaft Bt, as is also a gear B5. The main shaft of the machine is lettered C and is driven by a gear C2, meshing with the gear B3, through the collar of a clutch C1. A worm gear C3 drives the worm wheel El on the shaft E, presently to be referred to, and a gear C4, through another gear I)1 on the shaft D and worm D2 upon that shaft, drives a worm gear F1 turning the shaft F. On the rightfhand end of the shaft C (Fig. 1) is a bevel gear C5 driving another bevel gear G1, presently to be further described; a clutch C", the collar C7 of which is fastened to the shaft, connects the gear C5 thereto or throws it out, as may be desired.

Turning now to Fig. in connection with Fig. 1, it will be seen that the apparatus is located in a tank T, and in part consists, as already pointed out in my statement of invention, of two aprons, marked I and J. The construction of these is similar and is indicated in detail in Fig. 5, in which I is the sprocket chain, on the links of which collars I1 are located which carry metal rods I2, with rubber coverings The t avel of these aprons is in the direction shown by the arrows thereon, and it will be understood that there is a set of sprockets for each side of each apron or carrier (see Fig. 3), which occupies substantially the width of the tank T. I will first trace the course of the apron J, starting from the entrance to the machine, which is at the upper left-hand side of Fig. 2. A portion of the apron runs substantially horizontally over the sprockets K5 and K7, then running down to the sprocket K5, horizontally at the bottom of the tank to the sprocket K5, then over the smaller sprocket K4, then to K3` the smaller sprocket K2, then meshing with the larger sprocket K1, which is the driving wheel, upward to the eXit of the machine at the sprocket K; and then returning to the bottom of the machine, after delivering the goods therefrom, passes around the sprockets K11 and K1", back to K5. In order to keep a proper tension upon this apron, it runs over an idler sprocket K9, mounted upon an arm P pivoted at p; attached thereto is a rod P1 and a spring P2 secured in usual ways to the rod presses the latter upward and pulls upon the sprocket K, putting a tension upon the apron sufiicient to keep it tight.

The apron I, after passing around sprocket L5, at the upper left-hand corner, goes downward over the sprockets L5, L5, L, etc., passing around the driving sprocket Ll to the exit of the machine at the sprocket L, thence returning to the sprocket l] at the entrance. The tension device for this apron is lettered Q, an arm or lever carrying the sprocket L"5 at one end: passing through its other branch is a pin Q, around which is a spring Q2; the pin pivoted to the arm at y1, and the arm revolves about a pin [5 under the pressure of the spring, thus forcing the sprocket L5 downward and putting a suitable tension upon the apron I.

The apron J is supported between the sprockets by guide rollers H12, H12, etc.. which prevent it too much, and stiften it when it is oscillated, as presently to be described. The sprockets K, K5, L3, L5 are carried upon frames, the bars of which are marked il, H10, and which are pivoted respectively at h1, h1 on the frame A. This is the oscillating device to which I have referred, and which will be understood best from F Q, in connection with Fig. The bevel wheel G, on the righthand side of Fig. l, drives a shaft G, at the opposite end of which (see the left side of Fig. 4), is a gear G2, which revolves another gear G5 upon a stud G4. A counter-balance or pendulum H is connected to the gear Gr3 by a link h1; the weight YH1 is suitably proportioned to the work to be done, as will be understood, and adjusting means, consisting of holes z, is provided so that the weight may be raised or lowered as desired, a pin in one of the holes z securing it in place. At the upper end of the counterbalance is a partial gear H2 meshing with a similar gear H3 on a shaft llt. Referring now to Figs. 2 and 3, it will be seen that the shaft H4 carries a horizontal bar Il to one end of which is pivoted a link H5 extending and pivoted to the frame I 10 carrying the sprocket K5, etc.; while the other end of the bar H5 carries the link H5` attached to a bracket H7 upon the frame H5 carrying sprocket K3` etc. The operation of this part of the machine is as follows: The gear C5 on the right-hand side of Fig. 1 is loose upon the shaft C, the collar C5 being keyed to the shaft and constituting one part of a clutch C5. Yhen the clutch C5 is closed the bevel wheel C5 re* volves with the shaft C and in turn revolves the bevel wheel Gl, turning the shaft G (see Fig. 4). This turns the gear G2, and

gear G3 revolves, thus oscillating the counterbalance H, and through the gears H2, II3 rocking the shaftHt; the result of this motion is that the link HS is drawn upward as the link HG is pressed down, so that the t'wo frames carrying the aprons are first pressed together and then separated; the yarn which is carried between them, as presently to be explained, is first squeezed and then the pressure is released, so that the yarn again absorbs the liquid in the vat. By changing the gears G2, G3 the speed of this movement relative to the travel of the aprons may readily be controlled` and by altering, if desired, the distance of the crank pin from the center on the gear G3 by means well understood and which it is unnecessary to illustrate or describe, the extent of the oscillation may also be determined.

Referring now to Fig. 2, an important and valuable feature of the machine is found in the rolls IV, iV on the same shaft as and turned by the sprockets L2, If, on the left side of the machine. A detail of the operation of this part of the apparatus is found in Fig. 10.

1t will be seen that the apron I passes around these rolls, and as it does so carries with it the skeins of yarn X to be treated. This action prevents the skeins bunching in the opening between the aprons caused by the separation of the sprockets L, K, L2, K2, respectively; the space between the roll IV and the apron J, carried by the sprockets K4, ete., being so short that the skeins are certainly transferred to the apron J, without any opportunity to become bunched. At the same time the passage of the apron around the roll squeezes the skeins so that most of the solution is pressed out of them, and as they are released from this pressure and pass through the opening between the roll and the apron J, they again absorb the solution; this action tends to cause them to be thoroughly impregnated with whatever solution may be in the tank.

The yarn passes into the machine from the table N, on the left-hand side of Fig. 2, and leaves it on the right-hand side as the apron passes over the sprocket K (see Figs. 2 and 3). Upon leaving the apron at the sprocket K, it passes from the machine between the squeezing rolls. These latter are shown in Fig. 6 with their driving gear, and in Fig. 7 as to their construction. Referring to Fig.

- 6, the rolls F4, F are driven from the worm gear F1 through the shaft F, the upper roll being turned by the gear F3, taking its motion from the gear F2. The lower roll has a stationary bearing, but the upper roll has sliding box bearings, as will be obvious, and is forced down by levers F s, F6, only one of which is shown, the other being partly broken away for clearness of illustration;

these levers have lugs f2 which press down the sliding boxes of the rollers F5 by springs F secured to rods F7 pivoted at f1 in the frame A and bearing upon the eye in the end of the lever F 6. A nut and lock nut F 9 determine the tension of the spring.

The construction of the rolls is indicated in Fig. 7. A slot is cut in the metal roll F 5, for example, and in this slot is secured, by means of a rod F15 of Wood, the end of a suitable textile material. The machine is then allowed to operate and the roll rotates until a sufficient thickness of the material, in the judgment of the operator, is formed upon it, when the end is cut off. No securing means for the end is ordinarily necessary, because when the Wet yarn is squeezed the whole covering becomes soaked with the liquid and the end remains in place. The material which I have used and prefer is sail cloth or canvas, since I find that when it gets wet, it is soft enough not to injure the yarn, and yet it has sufficient bite to grip it and carry it through the rolls easily. As will be manifest, it will not be necessary to remove the rolls from the machines for recovering, since the old covering may be cut off from them and the stick F15 can be pulled out, or be driven out from one end and be removed by a few taps of a hammer.

At the entrance to the machine there is a feeding roll R, geared by gears R1, R2 to the sprocket K7 (see Figs. 2 and 4), which insures the certain delivery of the yarn to the opening between the aprons I and J.

The roll R seems at first sight to be unnecessary, because the action of the conveyer J, where it passes horizontally into the machine, carries the skeins of yarn to the opening between the aprons; but this is not so, because the roll straightens out the skeins, which in practice are liable to curl up, and prevents their being thrust back when they strike the apron I as it passes downward into the machine. In practice, there is not sufficient adhesion of the yarn to the traveling conveyer to prevent this occurring, and the skeins are thus apt to loecoine tangled or displaced, not passing through the solution evenly as they should. T he gears upon this roll and the shaft of the sprocket beneath it are necessary, in order to give the roll the proper direction of motion.

Referring now to Figs. 2 and 8, I show the mechanism which is used when a plurality of the machines is coupled together. Extensions A1 of the upper part of the machine register with the outside of the vat T1 of a second machine. From the shaft F, by means of a sprocket, is driven a transfer roller F13, carrying the yarn to the apron J1 of a second machine, as shown especially in Fig. 8. The yarn being brought up from the first vat on the apron J is transmitted to the squeezing rolls, and is then carried to the transfer roll F15, which in turn drops it upon the apron J1 upon the succeeding machine.

The transfer roll F12 is a desirable feature of the machine. By arranging the aprons in horizontal stages in the way which I have shown, and by oscillating them, so that the solution in the tank is caused to impregnate them very thoroughly, I am enabled to make substantial savings in floor space by shortening the machines; but it becomes necessary in doing this to bring the aprons to the squeezing roll at the end of the machine, at an angle greater than in those forms of apparatus in which a larger floor space is taken so as to accommodate a long apron. As the goods pass through the squeezing rolls F4. F5, they would have some distance to fall to the apron or carrier of the next suc* ceeding tank and might not always reach the proper place to enter the machine with certainty. The transfer roll obviates this diiliculty and carries them directly to the desired position. To adjust it to the desired relation between the squeezing rolls and the apron of the next tank, it is provided with slotted supports, in which its bearing may be moved about the center of the shaft F.

As these machines are driven by power and the load upon them varies considerably, an ample surplus of power must be provided; and as the squeezing rolls are under very heavy pressure, any operation about the machines is dangerous unless abundant facilities for stopping them quickly be provided. This I have arranged in the apparatus herein illustrated.

Referring to Figs. 1, 4 and 9, the stopping system bears, in general, the reference character M, with various exponents. In Fig. l the lever M is an ordinary shifting lever working through the link M15, the lever M11, pivoted at m5 and operating the collar of the clutch C1, connecting the gear C2 to the shaft C. A spring M9 of ample power to throw the lever is connected to the link M10 and as a factor of safety another spring M8 is also provided, so that when the lever M is released, it will certainly be operated. The lever M is held in place by a cam M1 formed upon a gear M2. A notch behind the cam holds the lever M in place, but when the gear M2 is revolved by moving the handle M", the inclined surface of the cam is presented to the lever M; the springs M1, M9 pull over the lever and shift the clutch C1, bringing the machine to an instantaneous stop, inasmuch as the worm gears C5, D2 serve as effective brakes. So much is old and common, but the improved arrangements neXt to be described I believe to be new with me. At M6 (see Figs. 1 and 4) is a board M5 mounted rigidly upon a shaft m2,' connected to the shaft at each end is a bell crank lever M5. On the side of the machine is a bar M15, connected at one end to the lever M4 and sliding in a guide m1, a stop m limiting its movement. One of the bell crank levers M5 connects with this bar at a slotted end m5. It will be obvious that if the hand is thrust against the board M5 with suflicient force to make it likely to get entangled in the machine, the lever M5 will, by the rotation of the shaft mi2, be thrown to the right in Fig. 1, throwing with it the bar M18 and thus operating the lever M4, turning the cam M1 so as to release the lever M, and throwing out the lnain clutch of the machine. On the other side of the machine the corresponding bell crank lever M5 is connected to a sliding bar M15, to which are also connected the handles M14, M12, the latter working against a spring M15. At the left-hand end of the bar M15 (see Fig. 4) is a lever M15 and a board M11 (see Fig. is connected to the shaft to which this lever is keyed. This board, as will be observed, is in front of the rollers F1, F5, which squeeze the yarn, and it will be obvious from the connections that Vif this board be pressed toward the rolls, it will throw the bar M15 to the right and operate the bell crank lever M5, thus, as already' explained, throwing out the main clutch of the machine.

In Fig. 4 the steam pipe S shows a source of heat for the fluid, while in Fig. 1 a valve V, operated by the pedal V3 through means of the bar V2 and a bell crank lever V1, serves to drain off the liquid from the vat when this is desired.
